Just in time to still make today's PR ;)

This change looks fine but as a future refactoring perhaps there should
be a wrapper for:

        ionic_dev_teardown(ionic);                                              
        ionic_clear_pci(ionic);                                                 
        ionic_debugfs_del_dev(ionic);

which pairs with ionic_setup() ?
